Novell GroupWise file
GWI is a database shortcut file format used by GroupWise. GWI files contain pointers to GroupWise database files, and may include a user ID, version, item type, message ID, or folder path. GWI files make it easier to find messages, records, and other information stored in GroupWise. If the database information is deleted, the .GWI file shortcut will no longer work.
